One of the worst 'punk' bands that I have ever had the displeasure of seeing on every emo magazine cover in North America.
Fall Out Boy is shit.

Guy One: Man, Fall Out Boy is so hardcore punk.
Guy Two: Haha, you like Fall Out Boy, you emo poser punk.
Guy One: I'm going to go cut myself now.

A pop punk band formed in 2001 in Chicago, Illinois. They consist of:
Patrick Stump: Lead Vocals, Guitar
Pete Wentz: Bass Guitar, BG Vocals
Joe Trohman: Guitar, BG Vocals
Andy Hurley: Drums

While currently very popular, they are one of the, if not the, most untalented and overrated bands in the world today. Fall Out Boy is an excellent example of just how bad radio-friendly rock has gotten over the years.
Guy: Hey, I'm going to the Dream Theater concert this Saturday. Wanna come along?
FOB fan: Nah, I got two tickets to the FALL OUT BOY CONCERT!!! OMG I CAN'T WAIT THEY ARE AMAZING AND SO HOT!!!!!!!!
Guy: Uh, yeah. Sure. That would be a no.
FOB fan: Oh, who is Dream Theater?
Guy: Never mind. They're too much for your little brain to handle.

just another reason for new trier kids to think they are better than everyone else
Fall Out Boy is often linked to emo. I don't know if this is fair to Fall Out Boy, but I do know that they aren't very good
